BRACE-CHAIR FOR RAILROAD-RAILS.

SPECIFICATION forming part of Letters Patent No. 494,243, dated March28, 1893.

Application filed February 20, 1890. Serial No. 341,121. (No model.)

To aZZ whom it may concern:

Be it known that I, WILLIAM MILTON BROWN, of Johnstown, in the county ofCambria and State of Pennsylvania, have invented a new and usefulBrace-Chair for Railroad- Rails, which invention is fully set forth andillustrated in the following description and accompanying drawings.

The object of this invention is sufificiently indicated by its title.

The invention will first be described in detail and then particularlyset forth in the claims.

In the accompanying drawings, Figure 1 illustrates the chair in endelevation with a rail, shown in cross-section, in place thereon. Fig. 2illustrates the parts shown in Fig. 1 in side-elevation. Fig. 3 is aview, in plan of the chair. Fig. 4 is a perspective view of the chair,showing in dotted lines the shape or form of the metal blank, out ofwhich the chair is preferably made. Fig. 5 shows said metal-blank incross-section, geometrically. Fig. 6 illustrates in perspective the keyor clamp which is used to secure the rail and chair together as the sameare used when laid in track.

In said figures the several parts are indicated by reference letters asfollows:

The letter A indicates the chair proper; a, a, the feet of the chair; B,B, the sides of the chair; I), that portion of the chair which forms thebrace for the rail; I) a portion of the chair bent over to form aretaining clip; F, the base, or rail-support-portion of the chair; 0, agroove or channel in said baseportion, or rail-support; and E, a key, ofthe shape shown in Fig. 6, which when driven into place, as seen in Fig.1, clamps the lower flange of the rail R firmly to the chair. The partsas lettered on, Fig. 5, show for the metal-blank, the corresponding, orrespective, portions of the chair, into which the similarly letteredparts of Fig. 5, are formed.

The purpose of the groove 0, and the peculiar conformation of the key E,are to secure a side-thrust and ample bearing in the chair, in additionto the holding-down bearing, and also to obviate all danger of the keyworking out of place. A further advantage is that said groove providesroom for the drop of the lower flange of the rail into the chair tofacilitate the attachment of the chair thereto without making the chairtoo wide; it being a desirable thing that the chair should not be widerthan the rail, in order to be nonobstructive to the paving-blocks of thestreet, these chairs being, in particular, suited forstreet-railway-use.

In Fig. 3 the letter .9, shows the space, in plan, between the edge ofthe brace 12 and that of the clip D.

The chair is applied to the rail in the following described manner: Thechair is attached to the rail so that the brace 19, comes well up underthe shoulder of the same, when the key E is then driven into place.

It is evident that the brace-portion of the chair, if desired, could beso bent or shaped as to come up under the headportion or against anyother of the outside portions of the rail, and it is also evident thatthe H- section, Fig. 5, could be rolled fiat across the whole face F,instead of with the groove 0 in the same, or made of malleable metal inwhich case the groove could be dropped in the chair in a subsequentdrop-forging or shaping process.

Having thus fully described my said improved rail-chair as of myinvention,I claim- 1. A chair, of rolled or malleable metal, forgirder-rails, having a portion of its rail-seat pressed downward so asto form a side-channel, and one side of the chair bent over saidchannel.

2. A box-chair, of rolled or malleable metal, for girder-rails, having aportion of its railseat pressed downward so as to form a side channeland one side of the chair bent over said channel.

3. A box-chair, of rolled or malleable metal, for girder-rails, having arail-brace on one side and a portion of its rail-seat pressed downwardto form a side-channel, in combination with a key inserted in saidchannel under a clip, as D, and over the foot of the rail.
